RAIL-DRESSING MACHINE.

To all whom it may concern:

Be it known that we, Mienxnn Moos, a subject of the King of Great Britain and Ireland, and residing at 309 Tigdon street, Princes llill, larlton, in the county of Bourke, State of Victoria, Commonwealth of Australia, engineer, and Tno'ams .lnrimnsox GILBEHL', a subject of the King 01 Great Britain and Ireland, and residing at 1 Min- .nie street. Brunswick, in the county of Bourke, State of Victoria, Commonwealth of Australia, dealer, have invented certain new and useful Ii'l'lprovements in and Relating to Rail-Dressing Machines, of which the following a specification.

This invention relates to rail dressing machines for instance of the kind described in the specification to our copending application Serial No. 538,519, and is particularly, though not solely, applicable to grinding tools.

Hitherto in rail dressing machines considerable difficulty has been experienced owing to the tendency which the tool has to follow, and thus exaggerate, rather than remove the existing corrugations 0r depressions in the rail.

The present invention has for its object to overcome this disadvantage and it consists in the provision of a series of rollers adapted to form an extended support for the tool and thus permit of the tool following a true path and removing the irregularities.

One mode of carrying out the invention as applied by way of example to a combined carriage and holder adapted to support a grinding wheel or wheels, is illustrated by the accompanying drawings, in which- Figure 1 is an elevation of a combined carriage and holder embodying the present mvention, while Fig. 2 is an elevation looking in the direction of the single arrow in Fig. 8. Fig. 3 is a plan of Fig. 1, and Fig. L is an elevation looking in the direction of the pair of arrows in Fig. 3.

The combined carriage and holder, consisting of a framework a is provided with removable trunnion caps b for accommodating trunnions on the rail dressing ma Specification of Letters Patent.

chine. and is supported on one side on an adjustable flanged wheel, 0, while on the other side are mounted grinding wheels, (I.

Secured to the framework in front of the grinding wheels (Z is a bracket 0 carrying a pin f upon which are mounted two plates 9 and h joined together and shaped to form a groove 2' wherein a series of rollers 7' are arranged upon pins Zr. \Vhen the machine is moving over a corrugated rail, these rollers ride over the tops of the corrugations and afford an extended or bridge like support for the tools and thus prevent the tools from dropping into the depressions.

If plain headed rails are to be treated, inner and outer side rollers are used adapted to make contact with the inner and outer sides of the rails. The former, 7, are mounted upon pins m in lugs n termed upon the plate while the latter m are. mounted upon inclined pins 0 in lugs 7) formed upon the plate It and are beveled so as to clear upstanding fish plates. These side rollers are removed when grooved rails are being treated.

The cz'irriage can be adjusted in a lateral direction by means of a hand wheel q operating a screw 9* which enters into the pin The screw r passes through a bridge 8 and is prevented from moving axially with relation thereto by means of collars 6 so that on turning the wheel 1 the carriage is moved toward or away "from the rollers. the play of the flanged wheel 0 permitting of this.

It is obvious that the above described system of rollers may be used with any kind of rail dressing machine and that the number of and method of attaching the rollers to the machine may be varied according to circumstances.

l laving now described our invention what we claim as new and desire to secure by Letters Patent is 1. In rail dressing machines, a combined carriage and holder secured to the machine, dressing means carried thereby, and a series of supporting rollers mounted upon said combined carriage and said rollers being directly in line with the dressing means holder means carried by said bracket for laterally adjusting the tool attachment.

In Witness whereof, we affix our signatures in the presence of two subscribing Witnesses.
